I'm new to contributing. I didnt write test cases, I"m not sure how to. The change is like ~10 lines of code. I do realize even one line of code can break a release. I sorted out the fix for the problem I was having and at least wanted to provide something to make things easier.

If there is a resource for how to properly work on python projects like this and build test cases, I'm eager to review it. I'm used to Java projects from like 15 years ago when I did a lot more team development.

Thanks for your contribution!

I've done minor change due to lint error and some issue in the set_llm_base_url method.
